Skywalker Ranch is the name of the workplace of film director and producer George Lucas. It is located in a secluded, but open area near Nicasio, California, in Marin County. The ranch is located on Lucas Valley Road, although Lucas is not related to the road’s namesake, who was a turn-of-the-century landowner in the area. The Ranch is not open to the public and keeps a low profile from the road. A gated road leads to the ranch.

Assembled parcel by parcel since September 1978, Skywalker Ranch has cost Lucas up to US$100 million, according to the Wall Street Journal. After neighboring ranchers complained that Skywalker Ranch was polluting the environment, Lucasfilm acquired 3,000 acres (12 km²) of adjoining land for a total of over 4,700 acres . Only 15 acres have been developed.

Skywalker Ranch is intended to be more of a “filmmaker’s retreat” than a headquarters for Lucas’s business operations. The headquarters of Lucasfilm, Industrial Light & Magic, and LucasArts are located in Lucas’s Letterman Digital Arts Center in the Presidio of San Francisco.Lucas does not live on the Ranch.-[source]
